Before you go back to the smog guy, get some seafoam use it on the vacume port on the pass side that connects to the break booster. directions are on the can, use most of the can. Put in some gas treatment stuff, with a 1/3 of a tank. Drive the shit out of it, make sure it stops smoking.

Then pull your plugs if the good spray them down with carb cleaner and put them back in. If not replace. Change your oil if its not that new.

Then I pull my o2 sensors and clean them with electric cleaner, reinstall.

Then check vacume lines for leakes.

The last thing is to pull your EFI fuse after all of this to reset your ecu.
drive out the rest of your tank.

Yes that could mean that it is, try soaking it over night in some diesel, or seafoam or some other solvent. Usually when you check it the next day the glass that you left it in is black. This will help loosen it up.
